$95 × 20% = $19
anything to ask please pm me
The original price was 7.
Chloe got a 15% discount; this means she paid 100-15 = 85% of the price. Letting x be the price, Chloe paid 0.85x.
Denise got a 20% discount; this means she paid 100-20 = 80% of the price. Denise paid 0.8x.
We know that Chloe paid 35p more; this gives us the equation
0.85x = 0.8x + 0.35
We do not want a variable on both sides, so we subtract 0.8x from both:
0.85x - 0.8x = 0.8x + 0.35 - 0.8x
0.05x = 0.35
Divide both sides by 0.05:
0.05x/0.05 = 0.35/0.05
x = 7
Let x and y be the 2 numbers
x + y = 10
x*y = 24

Answer:
x= 8.1353
x= 8.135 (rounded to the nearest tenth-thousandths)
x= 8.14 (rounded to the nearest thousandths)
x= 8.1 (rounded to the nearest tenth)
Step-by-step explanation:
<u><em>Note I am not 100% sure with my answer</em></u>
2 − ln (x − 8)= 4
−ln (x − 8) + 2= 4
−ln (x − 8) + 2 + −2= 4 + −2
−ln (x − 8)= 2
−ln (x − 8)/−1= 2/−1
ln (x − 8)= −2
<solve for the logarithm (ln)>
ln (x − 8)= −2
e^ln (x − 8)= e^−2
x − 8= e^−2
x − 8= 0.1353
x − 8 + 8= 0.1353 + 8
x= 8.1353
The common ratio of the GP is 3/2.
Step-by-step explanation:
- Step 1: Find first and second terms to find the common ratio, r = a(2)/a(1)
⇒ a(1) = 3^1-1/2^1 = 3^0/2 = 1/2
⇒ a(2) = 3^2-1/2^2 = 3^1/4 = 3/4
- Step 2: Find the common ratio
⇒ r = a(2)/a(1) = 3/4 ÷ 1/2 = 3/4 × 2/1 = 3/2
